This is not a discussion about casinos and how they win on every game in the house. That's both obvious and irrelevant.
All this is irrelevant when discussing whether or not the actual act of counting cards is a skill or not. I never said that casinos don't always win at their table games.
I brought up poker in response to you stating that it's not possible to be skillful at rolling dice because otherwise it would not exist in casinos.
By saying that, you implied that one cannot play a game of skill in a casino.
In other words, if you don't think one can become skillful at rolling dice, it needs to be for some other reason than the existence of craps tables in casinos.
Same way we're capable of throwing a curve ball or skipping rocks across a lake. Dice may require a lot more time and effort to master, but there's no question it can be done.
A roulette table on the other hand, you have no control over unless you're the operator. Tough to be skillful at something that you have no control over. And there is a way to beat the game of roulette regularly. Problem is, you need unlimited cash and a no limit table. All you have to do is double your bet every time. Point is the game itself is beatable.
Again, whether or not a person can walk into a casino and cheat at craps is irrelevant. This discussion is about whether or not a human being is capable of manipulating the outcomes of dice rolls.
